' tions, and has reference more particularly to a partition construction in which metallic studs of improved design are employed.

In the erection of partitions, it is desirable to use open metal studs which will permit the passage of pipes, conduits and ventilating and air conditioning ducts not only in a vertical but also in a horizontal direction. These studs are preferably constructed of metal to provide a fireproof partition. The studs should be low in cost, light in weight, easily erected, and be easily cut with an ordinary lathers snippers without the use of bolt cutters and hacksaws. For use around bathrooms and in certain other partitions, the studs should be reasonably sound insulating. The studs should be capable of supporting either a plaster wall, or a wall composed of composition boards,

such as gypsum or fiber boards.

An object of this invention therefore, is to provide a partition construction including lightweight, fireproof and inexpensive studs which have open webs to permit the passage of ducts, pipes, etc.

Another object of the invention is to provide lightweight metallic studs which maybe easily cut to the desired length by means of ordinary lathers snippers. 1

Another object of the invention is to provide a metal stud which may be attached directly to the floor and ceiling without the use of plates or runners.

A further object of the invention is to provide sound insulating partitions through the use of resilient clips on special metal studs.

A still further object of the invention is to provide a metal stud adapted to support either a plaster Wall or a wall made of composition boards; also to improve building constructions in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification, in which Fig. 1 is a perspective fragmentary elevation of the preferred form of my improved partition structure,

Fig. 8 is an elevation of the stud attached directly to the floor and ceiling.

Referring to the drawing by numerals,-a pair of channels III and II are secured in spaced, parallel relation with the webs I2 and I3, respectively, lying in parallel planes. In this form of stud, flanges I4 and I5, respectively, are turned outwardly and connector channels I6 are notched out at the ends to form outstanding lugs I1 which are secured, as by spot welding, to the flanges I 4 and I5 so as to rigidly secure channels I II andll in spaced, parallel relation. Connecmoditors I6 may be spaced at intervals desired, such as l-2 feet inorder to impart proper rigidity to the stud. The channels I and II are preferably constructed of lightweight, steel so that they may be easily cut to desired length with regular lathers shippers. If desired, short pieces may be joined to longer pieces to make complete studs, in the manner shown in Fig. 3. For this purpose, the flanges I4 and W of the stud are slightly spread apart -so as to receive the channels of the short stud length in telescopic relation, the two sections being rigidly secured together in adjusted posititin by means of tie wires I8.

Extension members 20 may be provided at the tops of the studs, said members .comprising channels 2 I in U-shaped form having a transverse cross channel 22 at the top. The channels 2| preferably have inturned flanges 23 which are telescopically received by stud flanges I4 and I in staggered relation as shown in Fig. 2 in order to impart maximum rigidity to the extension member, the channels 2| being secured to channels In and II in adjusted position by means of tie wires 24.

The bottoms of the studs are re-- ceived between upturned flanges 25 on basement to the floor of a building, or other building a 'framework. In nailing the channels 26 to concrete floors, stub nails are used and fiber board washers 26a are preferably interposed between the head of the nails and the channel web 21 to prevent breaking off of the nail heads. The channel flanges 25 are provided with spaced perforations 29 at about four inch spacing, so as to receive tie wires 30 to secure the bottoms of the studs to said flanges 25.'The channels 26 are telescoped together in end-to-end' position with end holes 28 in registry and secured together by of expanded metal or plaster base is secured to] channels it) and I I to receive a plaster coating 36 'or other wall facing element, and form a hollow partition. The plaster passing through the meshes of the expanded metal keys with the outstanding stud flanges l4 and i 5 so as to impart high rigidity to the flnished partition. Heating or air conditioning ducts 31, the like may partition, either in a horizontal or vertical direction. Thus, wash basins or other plumbing fixtures may be arranged on opposite sides of the partition and the connecting pipes will be entirely concealed by the hollow partition. If desired, resilient clips 39 may be attached to one or both of the stud channels l0 and II adjacent the connector channels I6, each of said clips having an'outstanding, notched, resiliently held arm 40 to which metal lath 4| is attached by means of tie wires 41. An arm 42 on said clip 39 is provided with U-shaped flanges 43 which embrace the channel provided to engage a connector I6 to flrmly and removably secure the clip to the stud. By the use of these resilient clips, a partition having high sound insulating value is produced for use around bathrooms and for certain other partitions.

In the form of partition illustrated in Fig. 6, spaced, parallel channels 48 and 49 are provided with inturned flanges 50 and 5|, respectively, said flanges being rigidly secured together by means of connector strips 52 which are spot welded thereto. Metal lath or stucco mesh 54 issecured to the channels 49 by tie wires 55, and exterior stucco 56 is applied to said expanded metal 54 to form the exterior wall face of a building. In order to form the interior wall facing element, perforated plates 58 are provided with inturned flanges 59 which are Welded to the webs of channels 48 so that said plates are spaced apart from said webs. The plates 58 are provided with a multiplicity of closely spaced perforati0ns'66 to receive board attaching screws 6i. Gypsum, flber or other natural or composition boards 62 are secured in face abutting relation against the plates 58 and are secured thereto by means of the screws ii. In erecting the partition, the boards are placed against the plates 58 and the board is pierced by conduits, pipes, or

a slender punch which "finds one of the perfora V tions 60. The punch is then withdrawn, and a screw inserted in the punched hole by means of a screwdriver until the board 6| is drawn up tight against theplates 58. applied over the exposed inside face of boards 62. As this partition is intended for the exterior walls of buildings, the channels 48 and 46 are made of considerably'heavier metal than the channels l8 and II so as to beload bearing. 'Ilhe partition shown in Fig. 7 is similar to that shownin Fig. 6 except that plates 58 and boards 62 are applied to both channels of. the studs to form a plasterless partition.

In many installatipns, it will desirable to freely extend through the hollow I III, a bearing lug 44 being Plastic paint is then eliminate the channel runners 26 (Fig. 8) and secure the studs directly to the floor and ceiling. For this purpose, nail holes 63 are provided in the webs of connector channels l6 for receiving large headed nails 64 driven into the floor 65. At the top of the stud, staples 66 are driven through the 'web of channel connector 22 into a joist 61 and straddling one of the flanges of said connector. A saving in the cost of channels 26 is thus eifected.

I would state in conclusion that while the illustrated examples constitute practical embodi- .ments' of my invention, I do not wish to limit myself precisely to these details, since manifestly, the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.
